CONCENTRATOR.

Application filed November 19, 1918. Serial No. 263,185.

To alwzomt may concern: table, the uppermost riflietapering from Be it known that l, GEORGE T. CooLEY, a say i in height to ,l, and the lowermost citizen of the United States of America, refrom 1 at the feed end to 2; and these siding at Joplin, in the county of Jasper riftles extend from the feed end and grad- 60 5 and State of Missouri, have invented cerually converge to the concentrates discharge tain new and useful lmprovements in Conend, where they are in consequence not only centrators, of which the following is a specireduced in height but also in width `and iication. capacity. These riffles are preferably My invention relates to an improvement slightly curved or panned, as shown in 65 in concentrators and it comprises a double Figure 4, and for this purpose a shim 5, deck machine, the upper deck or table being is inserted therebeneath to give the required a rougher and the lower onea finisher, there slope and curvature. being .means for conducting the concentrates rl`he numeral 6, indicates the feed boX in from the lower end of the rougher to the which the ore pulpis fed and 7 is the usual 70 feed end of the finisher. water box for creating the side wash upon My invention further consists in a rougher the sloping` surface of the table. having pan rifies disposed in fan like form The finishing table is indicated by the and extending throughout the length of the numeral 8, and is located below table 1, and table and of gradually increasing height may be of any of the well known types of 75 2G down the surface of the table. so-called sand tables as, for instance, the My invention also comprises, in conneclVil-fley type, in which the rilles 9 are of tion with the two decks or tables, a means uniform length at the head or feed end and for imparting a horizontal gyratory rotary terminate at the opposite end on a diagona motion to the feed end of one table and a line of separation, leaving a relatively 80 smart bump to the feed end of the other smooth surface 10.

Thisishorizontally located, as shown upon which the tables are supported. in Fiigures l and 2 and is provided with a Both tables are preferably alike in genbelt pulley 16, at one end, over which the eral dimensions and size, although' this is drive belt 1T, passes and with a bevel, gear not necessary. 18, at the opposite end, lthe teeth of which to The upper table 1, is a roughing table and mesh with the teeth of the bevel gear 19, on

its surface is partly riftled and the remainthe upper end of the drive shaft 20. The

. propose to adopt the ,bump variety and this is accomplished by the means of the rod 28, which ghas .a connection with the end of the table very much as ydescribed in :connection with table 1, that is, the same parts 12e and Q5 .serving as a fastening means. To reduce frictionto a minimum I employ ball bearings 29 and the forward end of this .sliding rod is yprovided with an ,anti-friction wheel 30, in position Eto bear ,against ,and traverse the double helical edge of the double cam 3l, which has the abrupt .shoulders or drops 32 which the roller 30 on the end of the rod the up per or concentrates `dis-v 2S, follows and the springs 31a are provided tocause 'the smart of* sharp bump upon the shoulders 32 of the double kcam. These springs 3l, are pccketed in the recesses 32 and there are preferably 4four of them to give therequired stiffness and their outer ends bear upon the collar 83 on the rod 28.

Motien is imparted through the'bel't 17 and transmitted toi the vertical drive shaft 20 and there being two bumps uponthe double cam Si, just twice as many impulses are given. to lthe ,lower .or finishing table that are to the ,upper or roughing table.

Vlfith. this double deck table .combining beth ra rougher and' iinislier .with pan riflies and rmeans for universal adjustment while in operation, l have provided a table of -very large capacity and efficiency and one in which the ore is successfully washed and dressed `without the necessity of 4re-handling.

Iclai-m:

The combination with a frame, of two tablesadjustably supportedat one end thereon, one having a fan-shaped arrangementof rifl'les kwhich taper and converge lengthwise ofthe table, and areiozf gradually decreasing height down the slope yof the table, means at thedischarge end for ,adjusting the ta'bles while in operation, and a single head motion common to both tablescomprising a shaft having a horizontally disposed. eccentric thereon, with means extending therefrom to one table, double cam with abrupt shoulders, and a spring-actuated sliding rod connected with the other table and adapted `to `be actuated thereby. f

In testimony whereof I aiHX my signature.
